Abstract
During the previous few years, phenomenon of bioconvection along with the use of nanoparticles showed large number of applications in technological and industrial field. This paper analyzed the bioconvection phenomenon in magnetohydrodynamic boundary layer flow of a Powell-Eyring nanoliquid past a stretchable cylinder with Cattaneo-Christov heat flux. In addition, the impacts of chemical reaction and heat generation/absorption parameter are considered. By the use of appropriate transformation, the goveming PDEs (nonlinear) have been transformed and formulated into nonlinear ODES. The resulting nonlinear ODES subjected to relevant boundary conditions are solved analytically through homotopy analysis method which is programmed in Mathematica software. Graphical and numerical results versus physical quantities like velocity, temperature, concentration and motile microorganism are investigated under the impact of physical parameters. It is noted that velocity profile enhances as the curvature parameter A and Eyring-Powell fluid parameter A/ increases but a decline manner for large values of buoyancy ratio parameter N, and bio-convection Rayleigh number Rh. In the presence of Prandt1 number P,, Eyring-Powell fluid parameter Al and heat absorption parameter 6, temperature profile decreases. Nano particle concentration profile increases for increasing values of magnetic parameter H, and thermophoresis parameter IV,. The motile density profile has revealed a decrement pattern for higher values of bio-convection Lewis number Lb and bio-convection peclet number P,. This study may find uses in bio-nano coolant systems, advance nanomechanical bio-convection energy conversion equipment's, etc.
